[00:19] <juxta|console> ping DanielRichman
[00:19] <DanielRichman> hi there
[00:19] <juxta|console> hey :)
[00:20] <juxta|console> sorry to bug you so late, was just going to ask something re CHDK
[00:20] <DanielRichman> go for it. I'm still awake
[00:20] <juxta|console> is it possible to have a script automatically run once CHDK boots?
[00:20] <DanielRichman> yes
[00:20] <DanielRichman> you have to set it up from within chdk's menu
[00:20] <DanielRichman> iirc
[00:20] <Randomskk> hey so on the burst calc I am adding the launch volume so you know how much helium to buy
[00:20] <Randomskk> can anyone think of anything else
[00:20] <Randomskk> burst alt, ascent rate, time to burst, neck lift
[00:20] <juxta|console> good idea Randomskk
[00:21] <Randomskk> that's five but six would be better
[00:21] <Randomskk> thoughts?
[00:21] <Randomskk> or I could just put launch volume in m³ and like whatever shit metric unit the yanks use
[00:21] <Randomskk> what do you buy helium in?
[00:21] <juxta|console> DanielRichman: okay, great - regarding booting CHDK automatically, the CHDK wiki seems a bit inconsistent - some pages say you can't auto boot on a card larger than 4gb?
[00:21] <juxta|console> cubic m or cubic feet
[00:22] <Randomskk> litre = m³ right?
[00:22] <juxta|console> no
[00:22] <Randomskk> balls
[00:22] <juxta|console> 1000L = 1m^3
[00:22] <Randomskk> obviously
[00:22] <Randomskk> that was a stupid thing to say
[00:22] <Randomskk> yup
[00:22] <Randomskk> so you buy helium in litres it seems
[00:22] <Randomskk> anything else? cubic feet?
[00:22] <juxta|console> cubic feet is the american way
[00:24] <DanielRichman> juxta|console: you can but you have to do some interesting formatting
[00:24] <DanielRichman> juxta|console: the auto load on startup is achieved by setting the lock switch on teh card (d/w, chdk unlocks it once it's started)
[00:24] <juxta|console> yeah - a small boot partition with a larger data partition
[00:24] <DanielRichman> that's some sort of hardware hack by canon to load stuff from the card
[00:25] <juxta|console> this 8gb card is still giving me issues, I think I'll just buy a 4gb card today and be done with it
[00:27] <DanielRichman> I did this:
[00:27] <DanielRichman> http://chdk.wikia.com/wiki/FAQ#Q._How_do_I_get_CHDK_onto_my_camera.27s_SD_memory_card.3F
[00:27] <DanielRichman> and this
[00:27] <DanielRichman> http://chdk.wikia.com/wiki/Bootable_SD_card#Linux:
[00:28] <juxta|console> pretty much what I'm trying to do - except my SD card is no longer working on my pc, though it works fine on the camera
[00:28] <DanielRichman> O/S?
[00:28] <juxta|console> [ 1806.325184] sdg: unknown partition table
[00:28] <juxta|console> ubuntu
[00:28] <DanielRichman> gparted?
[00:29] <juxta|console> gparted/fdisk, neither will read it
[00:29] <DanielRichman> make a new partition table then
[00:29] <DanielRichman> unless there's data on that disk you want
[00:29] <juxta|console> tried that, as soon as I eject and reinsert the card it's gone
[00:29] <DanielRichman> are there any errors in dmesg accompanying "unknown partition table
[00:29] <DanielRichman> ie. suggesting that the flash is borked?
[00:29] <juxta|console> nope, just that
[00:30] <juxta|console> it was working OK yesterday, but now it feels like giving me hassles
[00:30] <DanielRichman> when you say you "tried that" and eject/reinsert, did you do the "echo -n BOOTDISK | dd bs=1 count=8 seek=64 of=/dev/sdx1" step?
[00:30] <DanielRichman> does it even work still as a SD card (irrelevant of wehther you can use it to CHDK)
[00:31] <DanielRichman> if it's a SDHC you need a SDHC reader
[00:31] <DanielRichman> ((though that should cause it to just not read at all, rather than give the above error))
[00:32] <juxta|console> I was about to suggest the SDHC issue - but it's odd, as it would at least let me read it last night (it is an SDHC card)
[00:32] <DanielRichman> when I was working on the sd protocol for alien#1 I got the impression that a sd reader should totally fail to read a sdhc
[00:32] <DanielRichman> rather than sort of partly-succeed
[00:33] <Randomskk> http://www.srcf.ucam.org/~cuspaceflight/calc/
[00:33] <Randomskk> done
[00:33] <Randomskk> and pushed to ukhas github fork, too
[00:33] <juxta|console> hmm
[00:33] <DanielRichman> though it's possible that the reading it you experienced yesterday was infact the kernel buffering data?
[00:33] <Randomskk> by pushed I mean I clicked fork queue and clicked apply
[00:33] <Randomskk> much much nicer than pushing
[00:33] <DanielRichman> what would happen if you ejected & reinsrted?
[00:33] <Randomskk> it's a bloody lot of litres
[00:33] <DanielRichman> s/what would happen /could you still read it yesterday /
[00:33] <juxta|console> I actually had some success yesterday - I put CHDK on the card and it worked in the camera
[00:33] <juxta|console> but I hadnt set the bootable flag at that point
[00:34] <DanielRichman> so what's changed? unless the sd card flash has been fried overnight
[00:34] <DanielRichman> the rest is just software and making a new partiton table is starting fresh over
[00:34] <juxta|console> I have 3 readers - 2 flat out refuse to read the SDHC, this third one worked, but is no longer cooperating
[00:35] <juxta|console> nothing's changed so far as I can tell, the camera can still format the card and use it to store photos
[00:37] <DanielRichman> and if the camera formats the disk and stores photos, do changes made on the computer persist between ejects and inserts?
[00:37] <juxta|console> no
[00:37] <juxta|console> but they do make the card unreadable in camera
[00:37] <juxta|console> requiring another format through the camera firmware
[00:38] <natrium42> did you try barrel rolls?
[00:39] <DanielRichman> that is not good.
[00:39] <juxta|console> that's next on the menu natrium42
[00:39] <natrium42> :)
[00:39] <juxta|console> I'll get hold of an actual sdhc readier DanielRichman
[00:40] <DanielRichman> do you have any tiny or cruddy 128mb sd cards lying around that arn't sdhc jsut to play with?
[00:40] <juxta|console> this one is a cheap unmarked thing
[00:40] <juxta|console> yeah, all my <2gb cards work just fine in the reader & camera

[08:28] <m1x10> how can i get my highest alitutdE?
[08:29] <m1x10> at least when i recover the payload
[08:30] <jonsowman> well you can't really
[08:30] <m1x10> to know how far it have beeen
[08:30] <jonsowman> unless you implement code to watch altitude and save the maximum
[08:30] <jcoxon> arduino onboard eeprom?
[08:30] <m1x10> yeah
[08:31] <jcoxon> if altitude > last_max_altitude
[08:31] <jcoxon> sort of thing
[08:31] <m1x10> I have half eeprom empty
[08:31] <m1x10> yeah that i was thinking
[08:31] <jcoxon> you are only saving a long int or float
[08:31] <m1x10> yeah
[08:32] <m1x10> basically i will save time+coords
[08:32] <jcoxon> horus 6 went high
[08:32] <m1x10> so to combine with the time of the camera
[08:32] <m1x10> and know what was the highest pic

[08:36] <jcoxon> i know
[08:36] <m1x10> in a balloon flight it could be nothing more than a thousand
[08:36] <jcoxon> i'm saying its the best thing without adding a new piece of hardware

[10:24] <jcoxon> natrium has sped it up from back in the day
[10:25] <jcoxon> i think if you zoom out it'll plot less points on the map itself
[10:25] <jcoxon> but you still need to get all the points
[10:26] <juxta_> worked very well though!
[10:26] <juxta_> longest balloon train ever, hehe
[10:26] <jcoxon> hehe
[10:26] <juxta_> perhaps 100m on the train
[10:26] <juxta_> tomorrow is the camera payload
[10:27] <jcoxon> great
[10:27] <jcoxon> juxta_, i'm going to remove the car points from the map but leave the flight path
[10:27] <juxta_> jcoxon - we got an awesome altitude - 34km
[10:27] <jcoxon> so that when wb8elk launches he'll be second
[10:27] <jcoxon> then horus 7 will be third
[10:28] <juxta_> that was with a 1000g balloon and about 1000g payload
[10:28] <jcoxon> wow
[10:28] <juxta_> yeah
[10:28] <juxta_> looks like these chinese balloons might not be so bad
[10:28] <juxta_> clean burst too
[10:28] <jcoxon> oh cool a chinese one
[10:28] <juxta_> never had that before with the totex/kaymont
[10:28] <juxta_> will fly another tomorrow

[10:29] <Darkside> got a track?
[10:29] <Darkside> or a link to one lol

[13:32] <juxta_> there's a map of the contacts made today up on areg.org.au
[13:32] <juxta_> will pop it on the blog in a while
[13:32] <Randomskk> all I see on that site is a WAV
[13:32] <Randomskk> it's quite short too
[13:33] <juxta_> hmm that's odd
[13:33] <juxta_> www.areg.org.au
[13:33] <juxta_> don't know why the WWW A record doesnt match ;p
[13:33] <juxta_> or maybe a virtualhost, who knows
[13:33] <Randomskk> nice map
[13:34] <juxta_> it was incredibly successful - as was the chinese balloon
[13:34] Action: jcoxon hopes that randomsolutions might stock them
[13:35] <jcoxon> juxta_, if they are better 'quality' perhaps you could get a sneeky alt record
[13:35] <juxta_> I'll fly another tomorrow
[13:35] <juxta_> yeah
[13:35] <juxta_> I have a 2kg balloon here :)
[13:35] <jcoxon> if weather on your side go for very slow ascent
[13:35] <juxta_> yeah - will wait til the weather is just right
[13:36] <juxta_> tomorrow will have to be 5ms or so, otherwise we'll be driving all day
[13:36] <juxta_> got the car bogged today too, woohoo
[13:36] <juxta_> but saw the payload coming down in the field :)
[13:36] <jcoxon> :-)
[13:37] <Randomskk> oh, nice
[13:37] Action: jcoxon now understands why his broadband doesn't work - the wiring in the house is terrible
[13:38] <Darkside> juxta_: areg map is cool
[13:39] <juxta_> yeah, vk5zbr did that
[13:39] <Darkside> i should have let my dad know about it...
[13:39] <juxta_> we plan to fly the repeater again :)
[13:40] <juxta_> we also want to set up a big screen and deocding gear down at the launch site to act as mission control for next time ;p
[13:40] <jcoxon> haha
[13:40] <juxta_> they were managing everything today jcoxon, it was a real handful
[13:41] <juxta_> so many people getting on the repeater, as it's simplex they had to manage it and grant permission to talk etc
[13:41] <juxta_> plus making contact with us and others through the various repeaters and on HF
[13:41] <juxta_> amazingly they held contact through the balloon repeater down til about 400m
[13:42] <jcoxon> sounds very cool
[13:42] <jcoxon> good clean track on spacenear.us
[13:43] <juxta_> I'll double check to make sure it logged on SD in the payload then clear the tracker
[13:43] <juxta_> the 9000 points will only slow things down for others :)
[13:43] <Randomskk> we should be able to archive what's on the tracker
[13:43] <Randomskk> I mean in a long term should sense

[13:45] <jcoxon> will be back for ~4.30 for the WB8ELK launch
[13:46] <m1x10> if i wire two batteries in parallel I get both voltage and capacity increased?

[13:48] <Darkside> its just......

[13:48] <Darkside> i dunno how else to explain it, but you just know it
[13:48] <Darkside> lol
[13:48] <m1x10> lol
[13:48] <Darkside> though i guess the link could be made to capacitors if you like
[13:49] <Darkside> put two capacitors in parallel and the capacitance is the sum of each capacitors capacitance
[13:49] <m1x10> any website that shows how to wire 2 bats in parallel ?
[13:49] <m1x10> yeah Darkside
[13:49] <Darkside> m1x10: positive to positive, negative to negative
[13:49] <Darkside> nothing hard about it
[13:50] <m1x10> wire from 1st positive pole to 2nd positive pole?

[14:50] <DanielRichman> the sd card reader that sort of half worked half didn't is bad and doesn't conform to spec

[15:35] <m1x10> is there any company that sells tiny/small rockets ?!?!?!
[15:38] <Randomskk> estes
[15:38] <Randomskk> ?!?!?!?!?!
[15:39] <m1x10> estes???
[15:39] <Darkside> estes make rocket motors afaik
[15:39] <Randomskk> estes!!!
[15:39] <Randomskk> http://www.estesrockets.com/ ?!?!
[15:39] <Darkside> i got a few small ones before you had to have a license in australia
[15:39] <Randomskk> they make rocket motors and also rockets?!
[15:39] <Randomskk> no license needed in the UK, thankfully
[15:39] <Randomskk> I have a box of their motors
[15:39] <Randomskk> loads of fun
[15:39] <Darkside> made a small car out of lego and stuck a rocket motor in it
[15:40] <Randomskk> hehehe
[15:40] <Darkside> it went a long way, then something died and it went into a spin
[15:40] <Darkside> then the parachute charge thingo blew, blowing the lego car to pieces

[15:45] <m1x10> ok it says: Max Altitude: 1200 ft. (366 m)
[15:45] <m1x10> from ground
[15:45] <m1x10> but if u launch it from space?
[15:45] <m1x10> wouldnt go more ?
[15:45] <jcoxon> m1x10, indeed it would
[15:46] <jcoxon> a rocket launched from a balloon is known as a rockoon
[15:46] <m1x10> I think gravity is weak up there
[15:46] <m1x10> heh
[15:46] <jcoxon> no its not gravity, its more reduced drag
[15:46] <jcoxon> and the rocket motor runs more efficiently
[15:46] <m1x10> define drag :(
[15:47] <jcoxon> air resistance
[15:47] <Randomskk> air resistance
[15:47] <Randomskk> aww jcoxon beat me
[15:47] <m1x10> ok
[15:47] <m1x10> what is that rocket motor
[15:47] <m1x10> ?
[15:47] <Randomskk> the change in gravity is almost nothing, but the atmosphere is much thinner
[15:47] <Randomskk> so, less air gets in the way
[15:51] <m1x10> ok, this rocket: http://www.estesrockets.com/store/rockets/001302-cc-expresstm.html
[15:51] <m1x10> got the biggest alt
[15:51] <m1x10> 500m
[15:51] <m1x10> it could reach 1km at space
[15:51] <m1x10> though i dont know the physics to calc

[15:56] <juxta> jcoxon, my sd logging didn't work today, looks like I hadnt formatted the card corrctly - I'll dumb the spacenear.us database and then clear the tracks
[15:57] <m1x10> shit, estes dont sell outside us :(:(
[15:59] <Randomskk> just go to your nearest model shop
[15:59] <m1x10> but wait jcoxon, why is not gravity? Iirc gravity is less powerful up there
[15:59] <Randomskk> almost insignificantly less
[16:00] MoALTz (~no@ joined #highaltitude.
[16:00] <Randomskk> on the ground, acceleration due to gravity is about 9.81 m/s²
[16:00] <m1x10> anyway
[16:00] <m1x10> ok we know that
[16:00] <Randomskk> at 30km, it's 9.70 m/s²
[16:00] <m1x10> oh
[16:00] <m1x10> pfffffff
[16:00] <fsphil> it would certainly make orbit easier if that wasn't true :)
[16:01] <Randomskk> yes :P
[16:01] <m1x10> Randomskk, what nearest model shop?
[16:01] <Randomskk> m1x10: I don't know. whatever's near you. there's one in the town next to me, and a few big ones if I go into london
[16:01] <DanielRichman> it's understandably difficult to export rockets.
[16:02] <DanielRichman> especially from the us
[16:02] <fsphil> you launching rockets now m1x10?
[16:03] <m1x10> fsphil, no lol. I just thought I could reach more height if when the balloon bursts a rocket launches :):)
[16:03] <m1x10> DanielRichman, sure.
[16:03] <fsphil> aaah, that would be pretty cool
[16:03] <m1x10> and a camera recording it
[16:03] <fsphil> I thought about deflating the balloon slightly, and using a propeller like a helicopter to push it up further
[16:04] <m1x10> should be lol !
[16:04] <fsphil> not sure if there is enough air pressure though
[16:04] <m1x10> fsphil those rockets weight 60grams
[16:04] <fsphil> that's almost nothing
[16:04] <m1x10> yeah
[16:05] <m1x10> 60grams for another km or tw
[16:05] <m1x10> o
[16:07] <fsphil> put one of those little keyring cameras onto the rocket
[16:09] <m1x10> yeah
[16:09] <m1x10> but all those things will be planned for 2nd mission
[16:09] <m1x10> I want to keep 1st simple
[16:09] <juxta> I had a keyring camera on my payload today
[16:10] <m1x10> oh
[16:10] <juxta> and will fly it again tomorrow
[16:10] <Randomskk> you may find putting a rocket on a balloon is much, much harder to do safely than you anticipate
[16:10] <m1x10> video?
[16:10] <Randomskk> bear in mind that the potential safety implications are really serious.
[16:10] <m1x10> sure Randomskk, but what can I hit at 30km ?
[16:10] <juxta> yes, video
[16:10] <Randomskk> it's more a case of what you can hit coming down very very fast
[16:10] <fsphil> oh juxta, how'd everything go?
[16:10] <m1x10> juxta show me plz
[16:11] <m1x10> Randomskk im water landing.. dont forget that :)
[16:11] <Randomskk> m1x10: not if your rocket enters a ballistic trajectory at 30km
[16:11] <m1x10> traject what?
[16:12] <Randomskk> imagine if it fires sideways
[16:12] <m1x10> a
[16:12] <Randomskk> it will go a very long way and hit the ground very hard.
[16:12] <fsphil> how far could a 60g rocket go, sideways at 30km?
[16:12] <Randomskk> fsphil: consider how far they have to fall and how much speed they could get accelerating sideways
[16:12] <m1x10> juxta show me plz a video.. and tell me which model you have.......
[16:13] <Randomskk> a tiny rocket isn't likely to be the end of the world, but even then if it were over land and went straight down...
[16:13] <m1x10> hehe
[16:13] <Randomskk> even if the motor failed to ignite, a rocket is much more lethal than a payload going down. the whole pointy tip thing
[16:13] <fsphil> hmm deploying a parachute would be tricky too
[16:13] <fsphil> at 30km
[16:13] <Randomskk> you need to be very careful about everything
[16:13] <m1x10> I can stick the rocket inside in the middle of payload so it wont turn...
[16:13] <Randomskk> also, your GPS is liable to not work at that kind of acceleration
[16:14] <Randomskk> m1x10: unless the whole payload does, e.g. when a whole lot of thrust comes out the bottom
[16:14] <Randomskk> the payload is swinging about like crazy below that balloon
[16:14] <Randomskk> if the rocket turns on when it's swinging, it's not going to be pointing straight up
[16:14] <m1x10> yeah I have seen... its terrible.
[16:15] <MoALTz> how will it be triggered?
[16:16] <m1x10> well, thats still unknown...
[16:16] <m1x10> juxta r u there? m1x10 needs your video !!!

I was talking with my pal, who is involved with some UAV development, on Skype, when he mentioned, he could call the major, who is control the target range, where they testing the UAVs. We talked briefly, and the major was totally amused at my "weld-it, load it, blast it" attitude. I asked him, about the use of the range for HAB and rocketry testing, and he said it could be arranged
[17:24] <Hiena> . I asked how it will fit to the flight regulations, and he said these will not neccessary, because the modells will be registrated as projectiles or IED practice devices.
[17:26] <jcoxon> haha

[17:36] <jcoxon> but he is a big fan of dominoEX
[17:36] <jcoxon> this is a sparkfun module so super cheap

[20:09] <SpeedEvil> Oh - neat. WB8ELK has tracking all the way to the ground.

[20:32] <natrium42> SpeedEvil, quite impressive that you can track it fine with the cheap sparkfun transmitter
[20:36] <fsphil> I got one of those little modules from sparkfun ... couldn't make it produce anything but a really broadband buzz
[20:40] <SpeedEvil> yeah

[20:46] <Laurenceb> yo
[20:47] <Randomskk> hi
[20:47] Action: Laurenceb has been chainsawing
[20:47] <Laurenceb> electric chainsaws are suprisingly good
[20:47] <Laurenceb> never tried one before
[20:49] <Laurenceb> no power during zombie apocalypse :(
[20:49] <Randomskk> that would be their main disadvantage
[20:51] <fsphil> solar powered chainsaw?
[20:51] <Laurenceb> lol
[20:51] <fsphil> n/m -- blood would get on the panels
[20:51] <fsphil> :)
[20:52] <Laurenceb> oh something interesting i saw in a diy store - but not for sale - solar panels with spikes for sticking in your lawn + 2 axis joint
[20:53] <Laurenceb> then they had a weatherproof low voltage cable system, and ni-mh battery unit
[20:53] <Laurenceb> was powering the garden lighting
[20:53] <Laurenceb> must be possible to buy the stuff online somewhere...

[21:12] <Randomskk> oh?
[21:13] <Dently> I need some GPS Arduino code help
[21:13] <Dently> oops
[21:13] <Dently> I have a Motorola GPS and it need commands sent to it to get it into fix mode
[21:16] <Dently> what code can I use to send it a command like "@@Ce263a"
[21:17] <Randomskk> Serial.print(byte(64));
[21:17] <Randomskk> I don't know what the rest of those were ment to be
[21:17] <Randomskk> if that's all ascii, Serial.print("@@Ce^263a");
[21:17] <fsphil> yes! my antenna works .. did a little bit of morse, saw it on the websdr in .nl
[21:17] <Randomskk> but I think maybe one of those was a control character
[21:17] <Randomskk> fsphil: :O
[21:17] <Randomskk> epic
[21:17] <Randomskk> what radio is that? 817?
[21:17] <fsphil> yea
[21:17] <Randomskk> I really, realy should get an hf antenna setup
[21:17] DrLuke (~luke@pD951B458.dip.t-dialin.net) left irc:
[21:17] <fsphil> at the full 5 watts, it was only a slight trace
[21:18] <Randomskk> I have 100W of LF
[21:18] <fsphil> nice
[21:18] <Randomskk> and I've not transmitted or received anything on lf :cry:
[21:18] <Randomskk> I feel like I'm just neglecting the thing
[21:18] <fsphil> yep lol
[21:18] <fsphil> I feel bad about having two 817's
[21:18] <Randomskk> :P
[21:18] <Randomskk> I'm tempted to get an 817 for leaving at home for an automatic station here
[21:19] <Randomskk> once I get the vertical
[21:19] <fsphil> that's my plan too
[21:19] <Randomskk> but that'l have to come in a bit, when I'm paid a few more times
[21:19] <Randomskk> other things are higher up on the priority list
[21:19] <Randomskk> like overdrafts :P
[21:20] <fsphil> yea they're a little bit important
[21:20] <Randomskk> well it is interest free for the next three years
[21:20] <Randomskk> so it's not that critical but I'd rather not have it
[21:20] <Randomskk> and after that, there's always the vertical itself. plus a power supply for my existing radio. plus a new hard drive and more ram. plus a new multimeter.
[21:20] <DanielRichman> what radio do you have Randomskk ?
[21:21] <Randomskk> icom ic7000
[21:21] <DanielRichman> aah
[21:21] <Randomskk> it's very nice
[21:21] <Randomskk> but I don't find myself using it for much
[21:21] <Randomskk> which annoys me
[21:21] <Randomskk> like my full license
[21:22] <DanielRichman> I need to make the most of the 2 years of the hf antenna we have at school
[21:22] <Randomskk> eh, wherever you go to uni will probably have an even more epic setup
[21:22] <DanielRichman> though it needs a proper atu
[21:22] <Randomskk> cambridge has a sick rig
[21:22] <DanielRichman> true but from anywhere @ school I can walk 2minutes to this one
[21:22] <Randomskk> massive yagi on a rotator with essentially copper tape on steppers so it can adjust actual element length
[21:23] <DanielRichman> ...
[21:23] <DanielRichman> :O
[21:23] <Randomskk> http://www.steppir.com/
[21:23] <DanielRichman> can it shoot down pidgeons?
[21:23] <Randomskk> I.. I don't think it can shoot down pidgeons
[21:23] <DanielRichman> s/d//
[21:23] <Randomskk> .
[21:24] <Randomskk> but like, it can do great radio on anything lf in any dirn
[21:24] <DanielRichman> mmm
[21:24] <Randomskk> and they have a couple of radios, 400W tx (though the amps will do 1k), loads of hf yagis and verticals and stuff
[21:24] <DanielRichman> that website needs more pictures
[21:24] <Randomskk> by LF in all the above cases I mean HF
[21:24] <Randomskk> and by HF, VHF
[21:24] <Randomskk> so, that's silly.
[21:24] <DanielRichman> :P
[21:24] <Randomskk> but anyway they have loads of cool stuff
[21:25] <Randomskk> the one at surrey university is also quite well equipped, and very central
[21:25] <Randomskk> e.g. on the top floor of the e.eng dept
[21:25] <Randomskk> compared to cambridge's "in a shack out of town"
[21:25] <Randomskk> it used to be in town, but they wanted more space. on occasions they set up massive arrays of phased antennas in the field
[21:26] <Randomskk> DanielRichman: do you have a radio?
[21:26] <DanielRichman> not at home, no
[21:26] <DanielRichman> actually no, I lie, I've borrowed a local ham's ft790r
[21:26] <DanielRichman> and was using it to test the nim2 + xplain on a breadboard
[21:27] <Randomskk> cool
[21:27] <Randomskk> found any xmegas yet? :P
[21:27] <DanielRichman> they're on their very slow way
[21:28] Hiena (~Hiena@ left irc: Quit: -=Got bored from the net. Gone blowing up things.=-
[21:29] <Randomskk> hehe
[21:30] <Randomskk> right. I could work on my motor controller schematic, holiday homework C++ project, weather station firmware, habhub design, or anything on the next step down on the priority list
[21:30] <Randomskk> or I could even reboot to windows and play some games
[21:30] <DanielRichman> and the worst thing is that you don't have any five sided coins to flip
[21:30] <Randomskk> I know right
[21:30] <Randomskk> that would make it all better
[21:31] <Randomskk> I haven't rebooted my desktop since I started working
[21:32] <Randomskk> the holiday homework is boring and still needs a lot of architecture and work
[21:32] <Randomskk> but I'm damned if I'm going to do that the easy way
